to consider an alternative design using concrete rather than the scheme that was potentially planned for previous to that, which was a steel frame structure that used hydraulic dampers to control seismic motion. >> so, i met with my team. we worked hard. we came up with a great idea. let's take out the heavy steel structure, let's put in an innovative vertical post tension concrete structure, great idea. we did that. a lot of other things. and we came up with a price of 140 million. so, we achieved that goal. and, so, when we first started looking at the building, it was going to cost a lot of money. because of the way it was being built, we could only get 12 floors. we wanted more space for our employees. we ended up going and saying, okay, if we do a concrete building instead, which was web core's idea, we can get 13 floors, not 12 floors. the concrete doesn't require much space between the floors as a steel building does. and it could be cheaper. yes, more space, less money, great idea.
